Constructor & Destructor Documentation

SbVec3d::SbVec3d (void) [inline]

The default constructor does nothing. The vector coordinates will be uninitialized until you do a setValue() call.

SbVec3d::SbVec3d (const double v[3]) [inline]

Constructs an SbVec3d instance with initial values from v.

SbVec3d::SbVec3d (double x, double y, double z) [inline]

Constructs an SbVec3d instance with the initial vector endpoint set to <x,y,z>.

SbVec3d::SbVec3d (const SbVec3f & v) [inline], [explicit]

Constructs an SbVec3d instance from an SbVec3f instance.

SbVec3d::SbVec3d (const SbVec3b & v) [inline], [explicit]

Constructs an SbVec3d instance from an SbVec3b instance.

SbVec3d::SbVec3d (const SbVec3s & v) [inline], [explicit]

Constructs an SbVec3d instance from an SbVec3s instance.

Coin 2.5

SbVec3d::SbVec3d (const SbVec3i32 & v) [inline], [explicit]

Constructs an SbVec3d instance from an SbVec3i32 instance.

SbVec3d::SbVec3d (const SbDPPlane & p0, const SbDPPlane & p1, const SbDPPlane & p2)

Constructs an SbVec3d instance by combining the three given planes. None of the planes should be parallel to any of the other two, otherwise a divide by zero error will occur.

Member Function Documentation

SbVec3d & SbVec3d::setValue (const double v[3]) [inline]

Set new coordinates for the vector from v. Returns reference to self.

See also

getValue().

SbVec3d & SbVec3d::setValue (double x, double y, double z) [inline]

Set new coordinates for the vector. Returns reference to self.

See also

getValue().

SbVec3d & SbVec3d::setValue (const SbVec3d & barycentric, const SbVec3d & v0, const SbVec3d & v1, const SbVec3d & v2)

Set this vector to be the average of v0, v1 and v2. The vector components are weighted by the barycentric vector.

See also

getValue().

SbVec3d & SbVec3d::setValue (const SbVec3f & v)

Sets this vector to the single precision vector v, converting the vector to a double precision vector.

setValue().

void SbVec3d::getValue (double & x, double & y, double & z) const [inline]

Returns the x, y and z coordinates of the vector.

See also

setValue().

double & SbVec3d::operator[] (const int i) [inline]

Index operator. Returns modifiable x, y or z coordinate of vector.

See also

getValue() and setValue().

double SbVec3d::operator[] (const int i) const [inline]

Index operator. Returns x, y or z coordinate of vector.

See also

getValue() and setValue().

SbVec3d SbVec3d::cross (const SbVec3d & v) const

Returns the result of taking the cross product of this vector and v.

double SbVec3d::dot (const SbVec3d & v) const [inline]

Calculates and returns the result of taking the dot product of this vector and v.

SbBool SbVec3d::equals (const SbVec3d & v, double tolerance) const
